Good product but
Works very well. Loud sound. Only problem is that the battery runs out every two weeks. Replacing button cells can be challenging

One of the sensors does not work properly
The product is fine. The sound is loud and irritating which is actually good. Except one of them did not work properly. It kept ringing even though the door was closed and the distance between the sensors was very close.
